+*****************
+Warp i.MX7S board
+*****************
+
+This file documents the Buildroot support for the Warp i.MX7S board.
+
+Build
+=====
+
+First, configure Buildroot for the Warp i.MX7S board:
+
+  make warp7_defconfig
+
+Build all components:
+
+  make
+
+You will find in output/images/ the following files:
+  - imx7s-warp.dtb
+  - rootfs.ext4
+  - rootfs.tar
+  - sdcard.img
+  - u-boot.imx
+  - zImage
+
+Create a bootable SD card
+=========================
+
+In the U-Boot prompt lauch:
+
+=> ums 0 mmc 0
+
+This will mount the eMMC content in the host PC as a mass storage device.
+
+To determine the device associated to the eMMC card have a look in the
+/proc/partitions file:
+
+  cat /proc/partitions
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on the eMMC card. Launch the following
+command:
+
+sudo dd if=output/images/sdcard.img of=/dev/<your-sd-device>
+
+*** WARNING! This will destroy all the card content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/warp7/genimage.cfg.
+
+Boot the Warp i.MX7S board
+==========================
+
+To boot your newly created system:
+- put a micro USB cable into the Debug USB Port and connect using a terminal
+  emulator at 115200 bps, 8n1;
+- power on the board.
+
+Enjoy!
